ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Wed Jun 15 11:25:12 2022 +0200| [b468ddc75dde91cdb434457e7efc3d9efe40ddcf] | committer: Andreas Rheinhardt
avformat/matroskaenc: Don't waste bytes to Write Tag length fields
This is possible by using a dynamic buffer to write them;
said dynamic buffer is (re)used and reset as appropriate.
